Remarkable. Things definitely have changed with propane. Well, the last time I filled a propane car would have been early 1995, and that was the fill and spill method. I have no idea what goes on up here now. The taxi industry has abandoned it and my LTD is in the Ford dealership in the sky.

Couple years ago I think it was Roush offering F150s with the 5.4L converted to LPI (Liquid Propane Injection) Supposedly offered the same power as gasoline since it was injected as a liquid. Sold through licensed Ford dealers with a full warranty. I really liked them.
